EX6 - 5 MArch 2006 time of image 19:24:09, Moon dia is 31'06", Mars dia is 7", separation is 4°19'44". Moon alt is 65°33'00", Mars alt is 68°42'44". Use the Earthshine ti work with the Moon dia as the illuminated side of the Moon is extremely over exposed (to get Earthshine and stars/planet), thus is very distorted and NO GOOD for measuring information.

Seems this time must be ZD+5, so with that assumption, we get this data from USNO AA site.

Thus we have to figure out what the altitude means that is quoted above as it does not agree with Hc.
